Font too small

[Amn]

Does anyone know how to increase the font-size of the Netbeans? I am 
using NB13 under KDE Plasma. I did the installation following this link 
<https://kifarunix.com/install-netbeans-ide-on-debian-11/>. On another 
installation NB13's app font was big enough. Note: I mean the app's 
font, not the editor's font.

Changing the font-size on KDE did not change anything.
Thanks in advance.
